Although he contributed the creation many beautiful church paintings, Will God forgive his occasional drinking when that man stands before God?

(P.S) I don’t know the restiction of Russian Orthodox Church for its believer. But Dringing is not forbidden?
To my knowledge, I read in bible that drinking consists of “sin”. If I am right, almost every adult russian would be the offender of God’s forbidding!!(Because almost all of them drinks) Then everyone has to predict his or her time of death and has never fail to repent before priest about one’s sin of lifelong drinking to avoid Hell!
